How to remove two Linux distributions in dual boot?

Hello,

All you need to do is install your two new distributions over the old ones.

When reinstalling the first of the two new distributions, you'll need to make a decision during partitioning. You can:

• either reuse the existing partitions from one of the two old distributions, and possibly only overwrite / (to keep /home);
• or delete the old partitions and start fresh.

During this partitioning, you can also consider sharing certain partitions. In a traditional installation, a Linux system is installed on three partitions (/, /home, and swap).

• Regarding the swap partition, there's no need to create multiple swap partitions; you can perfectly share one for all your Linux distributions.
• As for /home, you can also share it, but be careful, as this can sometimes cause issues. Furthermore, if your two Linux distributions use common software but in very different versions, the configuration files for those programs may differ. As a result, the configuration files stored in the user directories (user profiles) may differ as well.

The only important thing is that by the end of the installation of this distribution, you ensure to install a boot loader (e.g., grub) to be sure you always have a coherent boot menu.

Regarding the second new distribution, again, you can reuse the partitions from your second old distribution (and particularly avoid formatting /home).

Good luck!

Hello,

Chrome OS Flex (formerly CloudReady) is the PC version of Chrome OS. It supports Android apps and has a few other features missing. There is excellent support for Linux applications with a Debian virtual machine that works very well.

Chrome OS Flex does not offer dual-boot installation. The entire disk is used by default. A good dozen partitions are created during installation, and you have no control over this process. In any case, only your personal folder is accessible; everything else is hidden and read-only. Therefore, all disk data is lost upon installation. So if you install it after another OS, it will be overwritten.

FydeOS is nothing more than a Chromium OS with a Chinese twist, with everything related to Google stripped away. Instead of needing a Gmail address to log in, you must register on a Chinese site. So, instead of your data being harvested by Google, it’s being harvested by the Chinese government... not much better! Support for Android and Linux applications is provided.

FydeOS does offer a dual-boot option at installation, but I don’t see how it could free up space to install on a disk fully used by Chrome OS without breaking it. It’s mainly designed for dual-boot installation with Windows.

Warning, with either of these two OS, you will lose the ability to run USB printers, scanners, or other devices requiring a driver since it’s not possible to install drivers on a read-only system.
